SIGNAL FDR PNEUIVIATIC TIRES.

Application filed February 3, 1912.

signed for Use in Connection with Pneumatic Tires of Automobiles, Autotrucks,

and the Like, of which the following is a specification.

This invention relates to signals and has.

for one object to provide for giving an audible signal or alarm to the driver of a motor-car that the pneumatic tire, to which this invention has been applied, has become deflated, on account of a puncture or other cause, to such an extent that further running his machine with the tire in this condition willprove injurious to the same. This and other objects are secured by the novel arrangement shown in the accompanying drawings, described in the specification, and pointed out in the claims.

Referring to the drawings, Figure 1 represents a sectional. view of an automobile wheel and tire to which the signal is attached. Fig. S2 is a front elevation of the same wheel. F'g; 3 is an enlarged view of the chain and means employed to connect the same to the tire and to the bell, and Fig. 1 shows a modification of the flexible connection. Fig. 5 shows a modification of the manner of making the connection between the chain 5 and the bolt 6. C, In the drawings, T is a tire, F the telly, S

l is a bell of any suitable construct-ion having'a projecting operating lever 2, which lever is under tension by reason of a spring within the hell (not shown) which tends to pull the lever in a' direction opposite that to which the chain 5 draws it; the bell is rigidly cl'amped onto one of clamp C. Passing through a perforation near the end of the lever 2 is an adjusting bolt 3 having adjusting threaded jam-nuts i ands,

6 is a bolt passing through pertoration in the side of the outer casing of the pneumatic tire in relatively the position indicated in the drawing, saidboltbeing held securely by the nut 7. Secured to the bolts 3 and 6 is a flexible connection composed of a closed coil spring 8. and chain 5., the tension of the coil spring being greater than. 2.7 LrJ" L 1.11 Llla'u or the spring within the oen and Wi'llCl'l Specification of Letters Patent.

actuates the lever. The spring 8 is held in connection with the bolt 6 by the nut T.

p The operation of my signaling device is as follows:

The pneumatic tire being infiated to proper running pressure and the bell clamped into position on one of the spokes, the connection 5-8 is brougljit under tension by means of the adjusting nuts and l so that the lever 6 oi the bell is drawn toward the tire into such a position that should the tension on the chain be slackened to a predetermined point the bell will ring by reason of the lever being acted upon by its own operating spring.

The novelty and utility of this invention will become apparent, forshould the pneumatic tire become deflated to a certain extent (see dotted'lines in Fig. 1) the tension on the flexible connection 5--8 will be slackened by reason of the tire flattening under the load of the motorcar. causing the bell to ring. l/Vitheach revolution of the defiated tire, the connection 5-8 will first be brought under tension and then released, causing an almost continuous ringing which will attract the attention of the operator of the car who is thus given immediate warningthat the the needs to be reintlatcd if he would save it from injury.

It is of considerable advantage in adjusting the tension on-the chain to test the workingot the bell without releasing the chain from its connection; this is done by press-- ing on the lever 2, the coilspring 8 readily permitting this to be done. I As the tension of the coil spring is greater than that of the spring which actuates the lever within the bell, this coil spring in no way interferes with the operation of this invention.

On account of numerous objections to the use of a rod or other rigid means for actuat ing the hell, I have chosen to describe the onewith the flexible connection; instead of the chain a metallic ribbon or flexible cord may be used.

In place of the nuts 7 and 7, the nut l), see Fig. 5, may be employed. This nut is provided with an ear integral therewith through which is a perforation for receiving the link of the chain 5. By this arrangement, the chain is permitted to lie closer to the tire.

The arrangement shown is simple and inexpensive, and, further has the advantage that if the alarm is sounded accidentally, on account of a'sharp turning of acorn-er by departing from the spirit or sacrificing any:

. the chain the motor-car or the tire striking an ob struction, it Will not necessitate the driver of the car stopping his machine in order to readjust the alarm, as would be required it the alarm Were sounded by the releasing or tripping ofa lever or catch.

The device may readily be applied to any automobile Wheel by simply making a small perforation through casing of the tire and passing the bolt 6 therethrough and securing same in position of the advantages of this invention.

Having thus described the invention, What and desire by Letters Patent I claim as new to secure, is-

1. In a tiresignal ofthe class the combination with a vehicle equipped with a pneumatic tire, of
